In neuroanatomy, the medial lemniscus (also known as Reil's band or Reil's ribbon (for German anatomist Johann Christian Reil) is a large ascending bundle of heavily myelinated[citation needed] decussating (crossing-over) second-order axons that extends throughout the brainstem. It represents the decussation of the internal arcuate fibers (which originate in the nucleus gracilis and nucleus cuneatus). The medial lemniscus is part of the dorsal column–medial lemniscus pathway that conveys information from skin mechanoreceptors to the thalamus.[1] Lesion of the medial lemnisci cause impairment of vibratory and touch sensation.[citation needed]
